Ok. Here is some Fun. This is the script that will produce zero without using any number in the code. Post your code if you find any such method

select 
	$,
	$+,
	$+.,
	-$,
	$*$,
	+$-,
	($),
	$.,
	($.),
	-+$-,
	+-$+.,
	-$+.+$.,
	'$,'-$+,
	'$,.'-$-.

Run the code and see the output. Each column produces zero as a result.
